HEATING-STOVE.

Specication of Letters Patent.

Application iild February 26| 1907. v Serial No. 359,348.

To all whom it may concern:

Be it known that I, HARRY WAGNER, citizen of the United States, residingat St, Louis, in the city of St. Louis and State of Missouri, haveinvented certain new and useful Improvements in Heating-Stoves, of whichthe following is a specification.

This invention relates to stoves and more particularly to such as aredesigned for heating purposes and which burn soft coal as fuel, thepurpose being to prevent marring the outside polished appearance of thestove as well as to economize in fuel and obtain a maximum percentage ofunits of heat from a given quantity `of fuel.,

For a full description of the invention and the merits thereof and alsoto acquire a knowledge of the details of construction and the means foreecting the result, reference is to be had to the following descriptionand accompanying drawings.

While the invention may be adapted to different forms and conditions bychanges in the structure and minor details without departing from thespirit or essential features thereof, still the preferred embodiment isshown in the accompanying drawings, in which:

Figurel is a perspective view of a heating stove embodying theinvention. Fig. 2 is a view in elevation of the body portion of thestove showing the jacket or encircling shell in section. Fig. 3` is ahorizontal section of the stove on the line -:c of Fig. 2.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawings by the samereference characters.

The invention relates most especially to the jacket, shell or casinginclosing the body of the stove, hence the latter may be of any type,pattern or make commonly employed for heating purposes. The acket orcasing l is of larger diameter than the body 2 of the stove so as toleave a space between the two for circulation of air which preventsburning or overheating of the acket or casing andl at the same timeinsures a greater volume of air coming in contact with the stove so asto carry off radiated heat. The jacket or casing 1 is preferably ofsheet metal such as steel or Russia iron which has a highly polishedexterior surface and which finish is maintained because theA jacket orcasing is prevented from overheating by the air circulating through thespace formed between said jacket and the body of the stove. The jacketor casing is supported in any desired way and maintains a fixed positionso that the space between it and the body of the stove is practicallyuniform. As shown, the stove is provided with cast metal rings 3 and 4to which the ends of the jacket or casing are fitted, so as to preventboth vertical or lateral displacement thereof. Projections 5 stud theinner surface of the jacket or casing and serve the purpose of spacingand bracing the same and providing d eflectors. The projections 5 are anintegral part of the casing and are formed' by partly cutting portionstherefrom andv pressing the same inward, forming openings 6 throughwhich air has ready ingress and egress. The inner ends of theprojections 5 touch the outer side of the stove body with the resultthat the casing is braced and centered. Projections 5 are comparativelywide so as to formv defiectors for the ascending current of air and saidprojections have a horizontal arrangement and taper towards their innerends so as to bring the smallest amount of metal possible in directcontact with the body of the stove to prevent conduction of heat to thecasing. While the projections may be arranged in any manner, it ispreferred to have them set staggering, 4thereby precluding the formation`of vertical channels and compelling the ascending air to take atortuous path with the result that the jacket is cooled to a minimumdegree, and a maximum amount of radiated heat utilized for eective workin raising the temperature of the room or apartment in which the heatermay be placed.

Having thus described the invention, what is claimed as new is:

l. In combination with a stove, a jacket or casing inclosing the sameand spaced take a tortuous path, the tapered ends of the projectionstouching the stove to hold the casing spaced therefrom.

3. In combination with a heater, a sheet metal casing surrounding thesame and having portions partly cut therefrom and pressed inward to formopenings in the side of the casing, and a plurality of inner projectionsextending across the space between the heater and casing, saidprojections having a horiz'ontal arrangement and tapered towards theirinner ends to bring a minimum amount of metal in contact with theheater.

,4. The combination of astove, rings carried by the stove, a casinginclosing the stove and spaced therefrom, the said casing being heldbetween the rings, and projections studding the inner side of thecasing, the said projections tapering to a point and engaging the stoveto hold the jacket spaced therefrom.

In testimony whereof I affix my signature in presence of two witnesses.

HARRY WAGNER.
